You know, if you're looking for the source of the pictures in someone Leo knows and maybe worked with who retained a connection with MITD until the end, you could do a lot worse than Amy herself. That would be pretty funny.
She mentioned some office conflict (well, virtual office anyway) with Heather but shut it down pretty quickly after that. Keith wasn't much help drawing it out -- he probably knew it all already. I like that Michelle chick, fooling everyone with her ditzy act. She knows what people want to hear.
